e6cd6caf31 cpu/x86/smm: Add weak SoC init and exit methods
This change provides hooks for the SoC so it can perform any
initialization and cleanup in the SMM handler.

For example, if we have a UART enabled firmware with DEBUG_SMI, the UART
controller could have been powered off by the OS. In this case we need
to power on the UART when entering SMM, and then power it off before we
exit. If the OS had the UART enabled when entering SMM, we should
snapshot the UART register state, and restore it on exit. Otherwise we
risk clearing some interrupt enable bits.

c5160986cf cpu/x86/smm,lib/cbmem_console: Enable CBMEMC when using DEBUG_SMI
This change will allow the SMI handler to write to the cbmem console
buffer. Normally SMIs can only be debugged using some kind of serial
port (UART). By storing the SMI logs into cbmem we can debug SMIs using
`cbmem -1`. Now that these logs are available to the OS we could also
verify there were no errors in the SMI handler.

Since SMM can write to all of DRAM, we can't trust any pointers
provided by cbmem after the OS has booted. For this reason we store the
cbmem console pointer as part of the SMM runtime parameters. The cbmem
console is implemented as a circular buffer so it will never write
outside of this area.

BUG=b:221231786
TEST=Boot non-serial FW with DEBUG_SMI and verified SMI messages are
visible when running `cbmem -1`. Perform a suspend/resume cycle and
verify new SMI events are written to the cbmem console log.

ad6157ebdf timestamps: Rename timestamps to make names more consistent
This patch aims to make timestamps more consistent in naming,
to follow one pattern. Until now there were many naming patterns:
- TS_START_*/TS_END_*
- TS_BEFORE_*/TS_AFTER_*
- TS_*_START/TS_*_END
This change also aims to indicate, that these timestamps can be used
to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

fa5ed059eb nb/intel/ironlake: Fix some quickpath init magic
Correct some Quickpath initialisation steps according to findings from
two different Intel reference code binaries as well as MCHBAR register
dump comparisons between vendor firmware and coreboot.

The MSR_TURBO_POWER_CURRENT_LIMIT information comes from EDK2 sources.

Tested on Apple iMac 10,1 (Clarkdale, aka desktop Ironlake), QPI init
now completes successfully instead of causing hangs before raminit.
Also tested on HP ProBook 6550b (Arrandale, aka mobile Ironlake), still
reaches payload (e.g. TianoCore).

49be1a9346 Revert "cpu/x86/lapic: Unconditionally use CPUID leaf 0xb if available"
This reverts commit ceaf959678.

The AMD Picasso SoC doesn't support x2APIC and neither advertises the
presence of its support via bit 21 in EAX of CPUID leaf 1 nor has the
bit 10 in the APIC base address MSR 0x1b set, but it does have 0xd CPUID
leaves, so just checking for the presence of that CPUID leaf isn't
sufficient to be sure that EDX of the CPUID leaf 0xb will contain a
valid APIC ID.

In the case of Picasso EDX of the CPUID leaf 0xb returns 0 for all cores
which causes coreboot to get stuck somewhere at the end of MP init.

I'm not 100% sure if we should additionally check bit 21 in EAX of CPUID
function 1 is set instead of adding back the is_x2apic_mode check.

TEST=Mandolin with a Picasso SoC boots again.

e9665959ed treewide: Remove "ERROR: "/"WARN: " prefixes from log messages
Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.

This patch was created by running

  find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'

and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with

  's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

Fixes commit 29c7622 ("cpu/x86/mp_init.c: Fix building with no

10796d8c1e src/cpu: drop CPU_X86_CACHE_HELPER and x86_enable_cache wrapper function
Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper
function around enable_cache which additionally wrote a POST code to
port 0x80 and printed a message to the console. This function was only
called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.

This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.

761e2ae676 cpu/x86/Kconfig.debug_cpu: drop HAVE_DISPLAY_MTRRS option
Since all x86 CPUs in tree have MTRR support, there is no need to guard
the DISPLAY_MTRRS option with HAVE_DISPLAY_MTRRS. Also all x86 CPUs/SoCs
have a display_mtrrs call at least somewhere in their code, so selecting
the DISPLAY_MTRRS option will always have an effect. All SoCs that don't
select RESET_VECTOR_IN_RAM have the postcar stage where it gets called.
The two AMD SoCs that select RESET_VECTOR_IN_RAM use the FSP2 driver
which contains plenty of display_mtrrs calls.

02164027b2 cpu/x86: Introduce and use CPU_X86_LAPIC
With using a Kconfig option to add the x86 LAPIC support code to the
build, there's no need for adding the corresponding directory to subdirs
in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added
(cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding
MTRR code selection patch and having verified that all platforms
added the MTRR code on that patch shows that soc/example/min86 and
soc/intel/quark are the only platforms that don't end up selecting the
LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y
which gets overridden to n in the Kconfig of the two SoCs mentioned
above.
